search for: subgraph

Dear All, I would like to seek for help on this issue: 1. I set par(mfrow=c(2,2)), hoping to plot 4 subgraphs in a whole graph 2. Each subgraph has its own x,y axes and each has x-axis label and y-axis label 3. moreover, subgraphs in the left column of the whole graph are all 3D, and have z axes and labels for z axes 4. subgraphs in the right column of the whole graph are all 2D 5. In each subgraph, x-a...

Hello, I'm running an algorithm for graph structural cohesion that requires a depth-first search of subgraphs of a rather large network. The algorithm will necessarily be redundant in the subgraphs it recurses to, so to speed up the process I implemented a check at each subgraph to see if it's been searched already. This algorithm is very slow, and takes days to complete on a graph with about...

Estimado Javier, Me alegra que hayas avanzado con tu error. Te respondo a esto último. La función induced.subgraph() espera como segundo parámetro una lista de los IDs de los vértices, mientras que tú le estás pasando una lista de 'edges'. Prueba lo siguiente: c <- induced.subgraph(datos.network, which(V(datos.network)$name == 'Casa')) Si entendí bien todo, debería funcionar. Un saludo,...

Dear All, I would like to ask a question on how to do overlay plots in each subgraph of xyplot. 1. I did simulations for m=1000, 2500, 5000, 10000, as the sample sizes. 2. for each sample size value m, 4 graphs are generated; each graph contains overlayed comparisons between 4 methods, 3. now I want put them into a 4-by-4 plot by xyplot, i.e., 4 sample size values, each of whi...

Hi all, I want to find all the mappings of one graph in another graph, based on their vertex labels Is there any way to do this in igraph based on vertex labels. (as far as i know Igraph allows the subgraph isomorphism based only on vertex and edge colors) Eg: graph 1: x(1) x(2) x(2) y(3) y(4) x(1) z(5) x(2) graph 2: x(1) y(2) # the brackets contain the corresponding vertex ids i would like my output to contain the two mappings from graph 1 i.e x(2) y(3) & x(1) y(4) Regards, Himanshu Mittal...

I need a function that builds subgraphs up to a limited distance from an input root node. I feel like this is a common enough task that there's probably an easier way to do it, but I'm still learning what tools are available to me in igraph and built my own solution. The code below was tested on a machine that didn't have is...

Hi R-users, I'm using igraph for an undirected graph. i used clusters() igraph function to know the component size(subgraphs) as shown bellow: c <-clusters(g)    # component sizes size <- sort(c$csize, decreasing=TRUE) cat("Top 20 cluster of the graph","\n") for (i in 1:20) {   cat(i,"  size:",size[i] ,"\n") } Can anyone help how to extract the subgraph components  based o...

...both directions to prove that ;) All that's been shown is that you can reduce it to a hard problem. You can also reduce it to 3-sat., but that doesn't mean anything unless you can reduce 3-sat to it. 5. The actual problem the outliner is trying to solve is actually more like > finding subgraphs that are isomorphic, making the problem even harder > (something like "given dags A and B does there exist a subgraph of A that > is isomorphic to a subgraph of B") > > This assumes, strongly, that this reduction is the way to do it, and also that SSA/etc imparts no structure...

Hi all, In lattice plots, is there any option to position the panel strips with text below each subgraph, instead of above? i.e. in: Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ long | Depth, data = quakes) ,is there any way to make "Depth" appear below the subgraphs, instead of above? I've been looking through the lattice documentation and the list archive bu...

...) me resulta un poco ?feo?. La siguiente forma me es mucho más agradable a la vista > a <- E(datos.network)[[inc(?Casa?)]] Los veo como un data.frame, correcto, varias columnas, una por cada categoría de E y su palabra correspondiente. Pero plot(a) no grafica una red. No lo es. > b <- subgraph.edges(datos.network, E(datos.network)[[inc('Casa')]]) Lo mismo, pero ahora es una red, lo grafico y me doy cuenta que faltan cosas, detecta el V que tiene el E, pero no toma ningún E de ese V que no coincida la palabra, en otra forma, A?B en la columna habitad tienen ?Casa? y en la columna...

...ombiner, and probably a few other passes as well. Benefits would include not missing cases missed by the current combiner and also more easily adapting to changes in the LLVM IR. All previous superoptimizers have worked on linear sequences of code. It would seem much better to operate on small subgraphs of the program dependency graph. I haven't worked out the details...

...ting scheduled between FOO and arg(r1). If BAR1 and BAR2 are unrelated operations, the following is a legal schedule : consumeArg(r1) consumeArg(r2) FOO BAR1 arg(r1) BAR2 arg(r2) This leads to illegal assembly program because the assembler expects FOO r1, r2 to appear together. How can I make the subgraph FOO->arg(r1)->arg(r2) be always scheduled as a group, i.e., prevent unrelated ops from getting scheduled in between? Thanks, Manjunath

...e neat to be able to do this somehow. When I define a sext_inreg instruction, LLVM does not match the sext node in the DAG with this, unfortunately. How is feats like this supposed to be done? Right now it seems that I need to do a custom lowering impelementation to replace the sext-SDValue with a subgraph with a 32bit virtual register, a copy to the low subregister, and then a sext_inreg node. Am I right? I would appreciate any answer, Jonas -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/201010...
